For whatever reason that switch inside my head that turns on the light to say I understand hashes just will not flick on! It's possible that I'm running before I can walk as I've forced my way through understanding and retrieving data from complex hashes, and written good few bits of code in the last few months, but I just cannot get it into my head how to build those hashes unless I explicitly hard code them.

Can you assist with a sample piece of code that may finally enable me to crack it?
